freedreno/cffdec: Add option to dump bindless descriptors

Browse Source 
cffdump --bindless would dump bindless descriptors. We don't know
what exactly is in the descriptors, so we dump all interpretations
for each of them.

Example:
    set[1]:
    UBO[0]:
        { BASE_LO = 0x23806420 }
        { BASE_HI = 0xc | SIZE = 0x2 }
    STORAGE/TEXEL/IMAGE[0]:
        { TILE_MODE = TILE6_LINEAR | SWIZ_X = A6XX_TEX_Z | SWIZ_Y = A6XX_TEX_X | SWIZ_Z = A6XX_TEX_Y | SWIZ_W = A6XX_TEX_W | MIPLVLS = 0 | SAMPLES = MSAA_ONE | FMT = FMT6_R8_G8B8_2PLANE_420_UNORM | SWAP = WZYX }
        { WIDTH = 12 | HEIGHT = 8 }
        { STRUCTSIZETEXELS = 1024 | STARTOFFSETTEXELS = 0 | PITCHALIGN = 1 | PITCH = 128 | TYPE = A6XX_TEX_2D }
        { ARRAY_PITCH = 4096 | MIN_LAYERSZ = 0 }
        { BASE_LO = 0xa5000 }
        { BASE_HI = 0x1 | DEPTH = 1 }
        { MIN_LOD_CLAMP = 0.000000 | PLANE_PITCH = 128 }
        { FLAG_LO = 0xa6000 }
        { FLAG_HI = 0x1 }
        { FLAG_BUFFER_ARRAY_PITCH = 327680 | 0xa0000 }
        { FLAG_BUFFER_PITCH = 64 | FLAG_BUFFER_LOGW = 0 | FLAG_BUFFER_LOGH = 0 }
        { 11 = 0 }
        { 12 = 0 }
        { 13 = 0 }
        { 14 = 0 }
        { 15 = 0 }
    SAMPLER[0]:
        { XY_MAG = A6XX_TEX_NEAREST | XY_MIN = A6XX_TEX_NEAREST | WRAP_S = A6XX_TEX_CLAMP_TO_EDGE | WRAP_T = A6XX_TEX_MIRROR_CLAMP | WRAP_R = A6XX_TEX_MIRROR_CLAMP | ANISO = A6XX_TEX_ANISO_2 | LOD_BIAS = 4.437500 }
        { COMPARE_FUNC = FUNC_GEQUAL | MAX_LOD = 4.000000 | MIN_LOD = 0.000000 }
        { REDUCTION_MODE = A6XX_REDUCTION_MODE_MIN | BCOLOR = 0x400080 }
        { 3 = 0x1 }
